preconfigured Debian SD cards

Hi , Now we have had a debian version of musical chairs where Lenny is now the obsolete , Squeeze is now the stable and Wheezy is now the testing.

Here is the script to make the Wheezy rfs, plus my personal tweaks.

Code:

#!/bin/bash

#Script hacked from the original Ubuntu one by Mark Gillespie (mark.gillespie@gmail.com)
#Version History:
#1.0 Initial Release
#1.1 Made debian build path relative, Did a check to ensure it does not go past stage 1 bootstrap on non-armv5 (sheevaplug) hardware, Reminder at end to delete debian build dir.
#1.2 small fix to arch detection.
#1.3 Added sanity check to ensure it's running under BASH, changed packages to include ssh, added some colour to the output, made ehe gziping non-verbose.
#1.4 Fix to ensure the serial console device gets created correctly. Added an apt package listing in the root of the filesystem, added move verbose messages, removed documents and man pages from the filesystem.
#1.5 Additional Cleanup, single variable to switch between lenny and squeeze.

#before we go any further, make sure we are running BASH, not that dumb mess that calling sh and getting dash thing that Debian/Ubuntu impmented.
test -n "$BASH_VERSION" || { echo "\033[0;31mERROR:\033[0;39m This script must be run using BASH and not other shells like DASH.\nIf you launched this as 'sh ./$0', try just launching it directly './$0' (after chmoding it +x).\n"; exit 1; }
